The perimeter of a rectangle is 85 ft. The length of the rectangle is two (x plus 16) and the width is 3x - 1. What is the length of the rectangle?

Answers

Answer:

The length of the rectangle is 27 ft.

Step-by-step explanation:

To determine the length of the rectangle, we will first determine the value of x.

From the question,

The length of the rectangle is 2x + 16

The width is 3x - 1

and the perimeter is 85 ft

From the formula for perimeter of a rectangle which is given by

P = 2(l+w)

Where P is the perimeter

l is the length

and w is the width

Then, we can then write that

85 = 2(2x+16 + 3x - 1)

85 = 2(5x + 15)

85 = 10x + 30

10x = 85 - 30

10x = 55

x = 55/10

x = 5.5 ft

Since the length of the rectangle is 2x+16, substitute the value of x

Therefore

l = 2x + 16

l = 2(5.5) + 16

l = 11 + 16

l = 27 ft

Hence, the length of the rectangle is 27 ft.

Leanna has a rectangular piece of fabric. The fabric is 24 inches wide and 40 inches long. Leanna folds the piece of fabric along its diagonal to form a triangular scarf.
What is the area, in square inches, of the triangular scarf?

Answers

Answer:

480 square inches

Step-by-step explanation:

width = base = 24 inches

length = height = 40 inches

area of the triangular scarf = 1/2 * base * height

= 1/2 * 24 * 40

= 480 square inches

Answer:

D = 9(x, y, z) = (2, 3, -4)

Step-by-step explanation:

A suitable calculator can compute the determinant for you. It is ...

D = 9

Then the values of x, y, z are ...

(x, y, z) = (Dx, Dy, Dz)/D = (18/8, 27/9, -36/9)

(x, y, z) = (2, 3, -4)

Fred started a new e-commerce business and borrowed 15000 for 12 years to get the business up and running. The interest is 18000. Find the rate

Answers

Answer:

The rate is 6.94 %

Step-by-step explanation:

Given;

Amount borrowed by Fred to start up the e-commerce, P = 15000

time of investment, t = 12 years

interest, I = 18000

The rate is given by the following equation;

P = IRt

R = P / It

where;

R is the rate

P is the principal

I is the interest

t is the time

R = (15000) / (18000 x 12)

R = 0.0694

R = 6.94 %

Therefore, the rate is 6.94 %

An object is launched at 20 m/s from a height of 65 m. The equation for the height (h) in terms of time (t) is given by h(t) = -4.912 + 20t + 65. What is the
object's maximum height?

Answers

Answer:

The maximum height is the y-value of the vertex.

h(t) = -4.9t² + 20t + 65

a=-4.9 b=20 c=65

h(2) = -4.9(2)² + 20(2) + 65

= -19.6 + 40 + 65

= 85.4

find the measures of one interior angle and one exterior angle of a regular polygon with 8 sides

one interior angle__________ one exterior angle___________

Answers

Answer:

one interior angle 135

one exterior angle 45

Step-by-step explanation:

Total measure of all angles in a 8 sided regular polygon = (n - 2)* 180

= ( 8 - 2 ) * 180

= 6 * 180

= 1080

Measurement of one interior angle = 1080 / 8 = 135

Interior angle and exterior angle make linear pair.

Measurement of one exterior angle = 180 - 135 = 45
